Reread the first six lines of the sonnet. If the first line is identified as “a” in the rhyme scheme, how should the remaining l
ines be identified? Shall I compare thee to a summer's day? Thou art more lovely and more temperate: Rough winds do shake the darling buds of May, And summer's lease hath all too short a date: Sometime too hot the eye of heaven shines, And often is his gold complexion dimm'd,
The last words of the first and third lines rhyme, and so do the last words of the second and fourth lines, making the rhyme scheme abab. The fifth and sixth lines do not rhyme, so the rhyme scheme for them is cd.
Thus, if the first line is identified as “a” in the rhyme scheme, the remaining lines should be identified as "babcd".
Well it all depends on what you're writing about. When you write your rough draft think about the feeling it gives when reading it over. Then if it feels right, give it a go. This might not help much but think about how you feel while reading it.
